Ubuntu 10.04

Under Preferences > Power Management I have changed the settings to never put the computer to sleep and never to put the display to sleep.

My display still goes to sleep and I am prompted for my password when I leave the computer unattended.

I would like to be able to hit the "Lock Screen" app I added to the top panel to lock my screen, but otherwise I would like it to just stay on.

Thank you.

Seems Ubuntu-specific. Should it not be moved to (Where I'm pretty sure it would be a dupe.) – David Krider Oct 23 '12 at 19:49

Check System>Preferences>Screensaver and see if "Activate screensaver when computer is idle" is checked.

Also, if you hit Alt + F2 and enter gconf-editor then navigate to /apps/gnome-power-manager/lock you can see if blank screen is checked.

I think that did it. Thanks. – CT. Jun 23 '10 at 18:48
Which one out of curiosity? – rybl Jun 23 '10 at 18:55
I believe the screensaver setting did the trick. I also did check in /apps/gnome-power-manager/lock and blank screen is not checked. – CT. Jun 23 '10 at 19:01

Things have changed since this post was submitted. Go to System Settings in the top right corner of your screen, select Brightness and Lock and set "turn screen off when inactive" to never.

hope this helps all future users.
